Letters Patent No. 96,069, dated October 19, 1869.

IMPRo'vED TESSELLATE'D FLOOR.

Tha Schedule xeferrad to in these Letters Patent and making part of the same.

To all whom 'it may concern:

Be it known that I, JOHN F. WORTH, of the city of Brooklyn, in the county of Kings, and State of New York, have invented a new and useful l'mprovement in Slabs and Blocks for Tessellated Floors; and Ido hereby declare that the following is a full, clear, and exact description ofthe same, reference being had to the accompanying drawings, which form part of this specification. v

Thisl invention relates to the securing together of slabs or blocks of tessellated wooden doors by tongues and grooves.

Said slabs or blocks, if constructed with their tongues or' tenons on them, or provided with tongues of the same material,would require unnecessary depth or thickness of the block for insuring a suiciency of strength-tothe tongue, more especially when the blocks are constructed for presenting the end of the grain to the wearing-surface. r

My improvement consists in providing each block with an angularly-formed metal tonguewhich projects from two or more of itssides, 'according to the form of' the block, and forming in its'remainiug sides corresponding grooves, for reception of the metal tongues lofthe blocks adjoining those sides, whereby a consideiable reduction in the thickness of the blooksmay be afforded without reducing the strength of their connections.

Refeiring to the accompanying drawings, Figure 1 represents a portion of a tessellated floor l formed of blocks constructed according to my invention;

Figure 2 represents a face view of one of the blocks,

. detached;

gigure 3 represents an edgewise view of the same; an Y,

Figure 4, asectional view of one of the blocks, taken in the line :c x, iig. 3.

Each one of said blocks A has a deep narrow groove,

s, formed in its edge, on all four of its sides.

Within this groove s, used upon two sides ofthe block, when square blocks are fitted and secured by glue, cement, or other suitable means, isarectangularlyformed metal tongue, a, as shown, the groove on the remaining sides of the v'block being left open, for the reception of the metal tongues of the blocks adjoining thereto. Y p Said rectangular tongue a, being constructed of met-al, is proportionately much stronger than wooden tongues, and consequently may be made much thinner, as shown in lig. 3, thereby allowingthe block itself to be made thinneiyas also shown in the same figure. With `iloors formed ofblocks constructed after this plan, a much greater depth or thickness of material may also be left between the outer surface ot' the floor and the said. tongues a, for the wearing away of the floor, than is practicable with floors formed of blocks of equal thickness constructed with wooden tongues.

The invention may also be applied to vblocks of hexagonal and other forms, by giving the metalvtongucs a form to correspond with that ot' the .blocks towhch it is to to be applied.

What is here claimed, and desired to be secured b Letters Patent, is 'lhe angular metal tongues, in combination with th blocks or slabs of wooden tessellated pavement, substantially as described, for thepurpose set forth.

JOHN E. WORTH.
